Study of unsteady flow simulation in aneurysm shape reconstructed with images for medical treatment

Abstract

In this report, the 3D shape was extracted from the image for medical treatment of the artery bow, and simulated by finite volume method. First, the technique to extract the blood vessel shape in accuracy was examined. The Marching cubes algorithm was used for the construction of the 3D shape from the CT images. The generated model for simulation had 100829 volume meshes. The changing flow was assumed to be a boundary condition of the entire. The numerical simulation was done, and the wall pressure and wall shear stress were examined.
